United Scientific Quantitative Electroscope

Measure the exact deflection angle for electrostatic repulsion.

• Wide walls to reduce the effects of air currents

• Well-balanced and sensitive vane
• Easy to read protractor
• Includes activity guide

The quantitative electroscope is ideal for measuring the strength of an electrostatic charge. A well-balanced vane rotates in response to an electrical charge. The angle measurements printed on the back show different positions in increments of 10° upto 90°. The stronger the charge the greater the deflection.
